Starter Relays

The starter relay is controlled by the PCM module via the starter enable control CKT 447 (YEL). If the PCM receives the correct password from the VTD module, the PCM module switches the starter enable control CKT 447 (YEL) to ground. The relay is energized if the ignition switch is in the START position and the gear selector is in the PARK or NEUTRAL positions.
